According to Criminal Defense and Traffic Attorney Tyler Chriscoe, sometimes it is legal to leave the scene of a crash but only in rare circumstances. For example, if staying would put you or anyone else in harm’s way. It is also alright to leave the scene should you require serious medical attention, not for a cut or bruise. But you can move their vehicle from the scene as long as you remain at the scene of the crash. Moving the vehicle should not cause more damage to the road.
